TO 4ALL WHOM IT MAY CONCERN:

Be it known that I, BRTON GIEENSIDE, of Fort Dodge, in the countyof'Webster, and State of Iowa, have invented a new and improved Gate;and I do' hereby declare that the following is a full, clear, andcxactdescription thereof, whichV will enable those skilled in the art to makeand use the saine, reference being had to the accompanying drawings,forming partof this specification, in whichi Figure I is a side view ofmy improved gate, part being broken away to show the construction.

Figure 2 is a detail sectional view, taken through the line :v x, fig.I.

Figure 3 is a detail View of one` of the catches and drops. v

Figure 4 shows a. modified form ofthe drop.

Figure 5 is a detail under side view of the hinge.

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve'the construction ot' gatesthat swing both ways, so as to make them more satisfactory and reliablein operation; and it consists in the combination and arrangement of thecog'ged plates, grooved cap, and the two guard-.pins with eachother; inthe combination and arrangement of the adjustable latch and weightedoperating lever with each other; in the combination of an additionallever with the operating lever and adjustable latch; in the combinationof an adjusting-screw and nut with the weighted lever and adjustablelatch; andin the combination of one or more catches and drops with eachother; the whole being constructed and arranged as hereinafter morefully described.

A is the gate, B is the front or catch-post, and C is the rear orhingepost.` D is the upper hinge, about the construction of which thereis vnothing new. E is the lower hinge, the platee1 of which is made witha downwardly-projecting flange, by means of which it is secured to thegate A. The forward edge of the plate e1 is cogged, as shown in iig. 5.-e2 is a plate which is made with a. downwardly-projecting ange, bymeans of which'it is attached to the post C. The forward edge of theplate e2 is` toothed or cogged, to mesh into the teeth of the plate el.e3 is a plate or cap attached to or formed solid with the plate. c2, andwhich projects over the plate e1, as shown in figs. l-and 5. e't are tworest-coge, upon which the gate rests or is pivoted while swinging. Thepart of the plates el and e2 between the rests e4 may be made curved, asshown in the drawings, or it may be made straight, and it may have cogsformed upon it, or may be made smooth, as may be desired. e5 are twoguard-pins, which are securely attached to the plate el, and enter andwork in-curved` grooves e6 formed in the under side ofthe cap or platee3. The grooves e.6 are curved in substantially the form shown in fig.5, that is to say, their inner parts are long arcs curving inward, andtheir outer parts are short arcs curving outward, so that the said pinsmay move freely through the said grooves while the gate is swinging. Fis the latch, which `passes through and works in a horizontal slot inthe front vertical bar of the lgate A. The rear end of the latch Fenters and is pivoted in a slot formed in the lower part of the lever Gby a-pin passing through the said lever and through one or the other ofthe several holes formed in the rear end of the said latch, so that itmay be adjusted to compensate for the swelling or shrinking of the gate.Upon the forward side of the lever G, a little above the latch F, isformed a projection or ear, by means of which the lever is vpivoted tothe front vertical bar of' the gate, as shown in'ig. 1. Thelevcr G ismade of such a form or is so weighted that its own weight will hold itslower 'end forward into such a position as to catchv .upon the catch orcatches attached to the post B. -g is a curved arm attached to the upperpart of the lever G, which enters and works in a curved hole formed inthe post B forits reception, to hold the said lever in a verticalvposition both when atrcst and when being operated. Y When the gate isplaced in situations where it may be convenient to open it from onhorseback, a lever, H, is pivoted Vto the upper part ofthe gate, itslower end bcingpivotedto the upper end of the lever G, and its upper endextending up into a position to be conveniently reached and operated. Iis a screw, whichpasses in through the forward side of the front bar ofthe gate, and is arranged in such a way that it may be free to turn,`but can move neither forward nor back. .I is a long nut placed` uponthe screw I, the forward end of which rests against u. projection orarm, g2, formed upon the lower'part of the lever, and which enters aslot in the gate-bar, so that the position of the level; Gr, andconsequently of the latch F-,Vmay be adjusted to compensate for theshrinking or swelling of the gate. K are latches having inclined heads,as shown in 5g. 2, which enter a recess formed in the post I3, and totheir inner ends are pivoted the upper ends of the drops L, which arepivoted tothe post B, or to thesides et' a case or box fitted into thesaid recess formed in the said post. The drops Il maybe pivoted to thecatch K either by having,- a socket formed in Vtheir upper' ends, asshown in fig. 3, or by means of a pivoting pin, as indicated in {ig.4.The drops Lshould be so pivoted as to more freely upon their pivotingpoints without coming in contact with or rubbing against the sides ofthe box or case. And they need be no heavier than `just suicient toforce out the catches K ivhcn pushed in by the advancing latch .of thegate. M is a stop pin, so placed as to prevent the drops from droppingdownso as` to push the catches out toe far. In case the gate is sosituated or constructed that it can swingbut onc way, but one movablecatch and drop may be used, the other` being stationary or beingreplaced by a stoppin or cleat.

Claims.

I claini as new, and desire to secure by Letters Patent- 1, rIhecombination and arrangement of the clogged or toothed platespel, e2, andthe cap or plate e3, havin,r two curved grooves, c, formed in its louterside to receive and guide the two guard-pins e5 attached to the plate e1with each other, substantially as herein shown and described, and forthe 4purpose set forth.

2, 'Ihe combination and arrangement of the adjustable latch F andweighted operating lever G -with each other and with the front verticalbar of the gate, substantially as herein shown and described, and forthe purpose set forth.

3. The combination of the lever IAI with the Weighted lever G- and latchRand with the upper part of the gate, substantially as herein shown anddescribed, and for the purpose set forth.

4. The combination of the adjustingscrew I and nut J with the lower partof the weighted lever G and with the front vertical bar of the gate,substantially as herein shown, and for Athe purpose set forth.

5.' The combination of one or more movable latches K and pivoted dropsL.\vith each other andjvith. the

post Bs substantially as herein shown, and for the purpose set forth.
